[NTG-context] Question about drawing flowchart using chart module

[Jeong Dal via ntg-context]

Dear all,

I tried to draw a flow chart using the module[chart].
Following the examples, I draw one.

The problem is that the size of the chart is not changed even though I changed 
the numbers dx,dy, width, height, and maxwidth in the \setupFLOWcharts

Please tell me how to resize the chart.

Thank you.
